Evaluation Kit for the MAX8529 (MAX8529EVKIT) (MAX8529EVKIT)

The MAX8529 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board demonstrating the MAX8529 dual, synchronized, step-down controller. The EV kit comes assembled with a circuit that steps down from an 8V to 13.2V input voltage, to output voltages of 1.8V and 3.3V. Both are capable of sourcing 3A. The switching frequency is set at 1.2MHz, and is adjustable from 600kHz to 1.5MHz with an external resistor. Alternatively, the controller can be synchronized to an external clock generated by another MAX8529 or a system clock. This device also features soft-start and soft-stop. The MAX8529 eliminates the need for current-sense resistors by utilizing the low-side MOSFET's on-resistance as the current-sense element. The adjustable foldback current limit reduces power dissipation during short-circuit conditions. The MAX8529 includes a power-on reset output to signal the system when both outputs reach regulation.
